0091608b08 Make the gate read jail_args and refuse a suite that dies partway
Two defects found in review, both of which made checks PASS more easily, so
neither ever went red.

GATE: is_covered() hardcoded its jail flags and never read the jail_args
marker that ci_mirror.sh and shell-tests.yml both consume. The features/lib
suite needs /usr/local/share and /etc/pki and aborts under set -e without
them -- but the coverage number still printed, because kcov had already
recorded whatever the dead run reached. The gate would have graded 44 libs on
a suite that never finished. It now reads the marker, keeps the historical
defaults for suites without one, fails closed on an empty marker, and passes
--fail-on-case-error.

Negative control: stripping the binds makes the gate exit 1 and restoring
them returns exit 0. Before this commit both cases exited 0 -- the gate could
not fail on an aborting suite.

HASH CACHE: the _t_unstub helper written earlier today for the transcribe
harness was needed in features_harness.sh too. Two assertions were vacuous --
test_dwm_config's "verify still reports when dwm is absent", and
test_rpi_nc_ca's uname removal, where a cached uname left every later branch
running under a faked Darwin. All four `rm -f "$TEST_TMPDIR/bin/` sites in
the repo were audited; the other two are sound (one probes with [[ -f ]], the
other runs in a subshell).

No measured figure moved: dot_resolver_install.sh still 39/39 = 100.00% with
real absence enforced, so its off-allowlist clearance holds.

d277369aca Cover clean_audio_filters.sh (89.25%), completing testsAndMisc-bash/lib
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
A 38-assertion suite for the last lib in the directory without one. Every
one of its five libs now has a suite; at the start of the session it had
none. 118 assertions across the directory, 0 failures.

build_filters is asserted on the EXACT filter string it emits, because that
string is the lib's entire product. An arnndn chain missing its mandatory
48 kHz resample, or a preset silently falling through to no dynamics, yields
worse audio and never an error -- nothing else would catch it.

Every exit code is pinned: 1 for a missing command, 11 for "RNNoise required
but unavailable" (refusing to quietly fall back to afftdn), 8 for an ffmpeg
whose afftdn lacks md=.

Measured 83/93 = 89.25%; it stays on the allowlist. All ten uncovered lines
are the documented under-report, not gaps: an `exit 66` sentinel proves
require_cmd's lines 37-38 execute, 52-58 are a multi-line array literal (the
confirmed continuation-line artifact), and 129 is an empty `*) ;;` arm whose
branch has a passing assertion. The gate uses the measured figure, so the
exemption stands regardless.

154b416617 Clear transcribe_venv.sh: 100%, off the allowlist, 104 -> 103
A 29-assertion suite covering all six functions. transcribe_venv.sh measures
53/53 = 100.00% through the directory runner, and check_shell_coverage.sh
passes it with the exemption deleted.

Assertions are on recorded ARGV because which index a pip install points at
IS the behaviour: the OpenNMT cu12 wheel index on the NVIDIA path, the
CPU-only torch index for diarization (forced to avoid mismatched CUDA
builds). "pip was called" cannot see either.

generate_test_audio's four-deep fallback chain is covered by failing each
generator in turn. Every stub materialises the wav, because the chain
advances on `[[ ! -s $tmpwav ]]` -- a record-only stub would silently
exercise the branch after the one under test.

One assertion was wrong and got corrected rather than forced: I claimed a
wholly-failing pip still returns 0, but the final `python "$PY_HELPERS"
deps-installed` carries no `|| log`, so it does not. The suite now asserts
what the subject actually guarantees -- all four warnings emitted, no earlier
failure aborting the run.

SC2016 fixed at the source with a quoted heredoc, not suppressed.

b91be3099d Clear unity_handler.sh: 100%, off the allowlist, 105 -> 104
The first allowlist removal of the campaign this session. unity_handler.sh
measures 32/32 = 100.00% through its directory's runner, and
check_shell_coverage.sh passes it with the exemption DELETED -- the real
gate, not just the measurement.

HARNESS BUG found getting there: bash caches executable locations in a hash
table, so `command -v foo` keeps succeeding after foo is removed from the
stub dir. Every "tool is missing" test was therefore running as a "tool is
present" test, asserting the opposite of its own name while looking
plausible. Reproduced minimally: after rm, STILL FOUND; after `hash -r`,
gone.

A _t_unstub helper now removes the stub and clears the table. The two suites
committed an hour ago had the same defect and are corrected here --
test_transcribe_pkgmgr.sh goes from 15 to 18 passing assertions, so three of
its checks had been vacuous. This is exactly the failure the campaign exists
to catch, found in its own test code.

`basename` joins the restricted PATH because the SUBJECT calls it; the suite
avoids needing `tail` via a parameter expansion instead, since every binary
in that PATH is one more thing a stub's shebang can trip over.

transcribe_deps.sh (92.31%) and transcribe_pkgmgr.sh (98.00%) re-measured
unchanged and stay on the allowlist.

ac1cf57656 Give testsAndMisc-bash/lib a harness; cover transcribe_deps and _pkgmgr
The directory held five allowlisted libs and no tests. It now has a harness,
a runner, and suites for two libs: transcribe_deps.sh (the fourth
hardest-first target, 48/52 = 92.31%) and transcribe_pkgmgr.sh (49/50 =
98.00%). Both stay on the allowlist. 15 + 18 assertions, 0 failures.

No jail is needed here and no jail_args marker is created: every branch turns
on `command -v <manager>` and every install goes through sudo, both
intercepted by a PATH stub dir. Verified the runner exits 0 when invoked
bare, which is how both gates call it.

The harness REPLACES PATH rather than prepending. This host really has
pacman, and a prepended stub dir cannot HIDE a binary, so every "manager not
installed" case would have asserted nothing. `bash` and `env` are in the
private coreutils dir for a non-obvious reason: every stub's
`#!/usr/bin/env bash` shebang resolves through that restricted PATH, and
without them each stub died with "env: 'bash': No such file or directory"
while looking exactly like a coverage gap.

Assertions are on recorded ARGV rather than on the call happening, because
which packages a branch installs is what differs between distros --
pacman gets python-virtualenv where apt gets python3-venv.

Three assertions aimed at the libsndfile branch were REMOVED rather than left
green-but-vacuous: /usr/lib/libsndfile.so exists on this host, so
need_libsndfile is legitimately 0 and lines 19/52/53/55 are unreachable
without a jail that hides the library. The limitation is written into the
suite instead of asserted around.

92678c9506 Cover rpi_nc_ca.sh (98.63%) and bind the two paths its suite needed
A 26-assertion suite for rpi_nc_ca.sh, third in the hardest-first order. All
five OS branches are exercised by seeding the marker file each one tests for
inside the jailed /etc, plus a uname stub for Darwin; both NSS stores and all
three Firefox outcomes are covered.

SHARED-FILE BUG: the Debian branch does `mkdir -p
/usr/local/share/ca-certificates` and jail_args bound only /usr/local/bin, so
the suite aborted there under set -e. /usr/local/share and /etc/pki are now
bound. jail_args is shared by every suite in the directory, so all five libs
were re-measured: dot_resolver_install.sh still 39/39 = 100.00%, and
rpi_nc_install.sh, dwm_config.sh and aw_autostart.sh are unchanged. An
over-aggressive mount looks exactly like unreachable code, so this check is
not optional.

That bind also unblocked the runner for the whole directory: with the old
args the run exited 1 before nc_php.sh could be measured at all.

Measured 72/73 = 98.63% through run_all.sh, which is the exact subject
is_covered() builds -- the gate's own view -- so the lib STAYS on the
allowlist. The single test file alone reports 73/73 = 100.00%, both figures
reproduced twice. The one-line delta is line 141, the first line of
show_help's heredoc BODY: not a statement, so the denominator is wrong rather
than a test missing. Excluding heredoc bodies from the denominator is the
next piece of work; it is what stands between this suite and the bar.

26afe4390c Cover aw_autostart.sh (82.93%), executing the script it generates
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
A 25-assertion suite for aw_autostart.sh, second in the hardest-first order.

The generated i3blocks status script is asserted by RUNNING it against
stubbed pacman/pgrep across all four of its branches -- uninstalled,
installed-but-stopped, running, installed-via-package -- rather than by
grepping the heredoc's text. A heredoc that emits syntactically broken bash
passes a text check and fails in front of the user.

One assertion was silently testing nothing at first: aw-qt is genuinely
installed at /usr/bin/aw-qt on this host, so the "not installed" case found
the real binary through the PREPENDED stub dir. PATH is now REPLACED for that
one case. The suite went 24-passed-1-failed -> 25-passed-0-failed, and the
gate caught it rather than the number.

Measured 68/82 = 82.93%; it STAYS on the allowlist. The residue is the
`[[ $EUID -eq 0 ]]` false branches, which are unreachable inside the jail
because the process is uid 0 there, plus the documented kcov under-report --
an `exit 44` sentinel proves create_i3blocks_status runs to completion while
its lines 145-162 report zero hits. Third lib to show it.

768e73249d Cover dwm_config.sh and fix its unreachable upstream-drift warning
A 27-assertion suite for dwm_config.sh, the highest-scored remaining
allowlisted lib. It drives the lib for real inside the jail: rewriting dwm.c
with perl, appending to config.h, compiling with cc and installing into
/usr/local/bin. The generated content is asserted, not just the call.

LATENT BUG, found by writing the test: apply_fullscreen_confine_hook does
`on=$(grep -c 'pconfine-auto on' "$src")`, and grep -c exits 1 when the count
is zero. The caller runs `set -euo pipefail`, so the function aborted at that
line exactly when the count was zero -- which is precisely when the
"setfullscreen/unmanage were likely refactored upstream" warning three lines
below was the thing needed. The warn branch was dead code in the only
situation it exists for. Both call sites now use `|| true`, and the suite
asserts the warning fires.

Measured: dwm_config.sh 35/73 = 47.95%. It STAYS on the allowlist -- the bar
is 100% and it is measured, not asserted.

That number is an under-report. An `exit 43` sentinel proves build_install,
build_pointer_confine, write_session_files and verify all execute inside the
jail while kcov reports their bodies at zero hits. One kcov artifact is now
CONFIRMED against a minimal repro: continuation lines inside a multi-line
quoted argument (the `perl -0777 -pe '...'` blocks) are counted as
statements that never run, which is the wrong denominator. A sixth
hypothesis -- that the exec-ing sudo shim or a pipeline loses the trace --
was tested and disproven. The two-strike time-box on this hunt is spent;
docs/shell-split-verification.md records what is known, including the
exit-sentinel technique for telling a tracing failure from an aborted suite.

08b58794e2 Teach both lib/tests gates to run jail-requiring suites
ci_mirror.sh and shell-tests.yml discovered every */lib/tests/run_all.sh and
invoked it bare. The features/lib suite refuses to run bare -- that guard is
what stops it rewriting the real /etc -- so the pre-push gate blocked all six
pending commits, and CI would have gone red on the same suite the moment they
landed.

A suite now DECLARES its jail requirement with a jail_args file beside its
run_all.sh, holding the --bind/--seed-* flags it needs. Both consumers branch
on the marker. The 105 still-allowlisted libs were scored on root ops and
system writes, so most future suites will need the jail too; naming the path
in two runners would drift, which is the failure ci_mirror.sh's own comments
say it exists to prevent.

Both branches fail closed: a marker present but empty is an error, not a skip.
Verified the extracted flags reproduce the independently measured
dot_resolver_install.sh 39/39 = 100.00%, and that the other five suites still
pass bare.

0e843c2a5f Cover rpi_nc_install.sh and fix two latent bugs in the nc_php suite
rpi_nc_install.sh is one 200-line function that apt-installs 24
packages, seeds MariaDB, rm -rf's /var/www/nextcloud, rewrites Apache
and PHP config and installs a www-data crontab. 29 assertions, run for
real inside the jail. The destructive step is the point: a bug in
`rm -rf /var/www/nextcloud` is invisible to any check that does not
actually run it.

Two latent bugs in the ALREADY-COMMITTED nc_php suite, both found by
finally reading its assertion results instead of only its coverage
percentage. It was failing 2 of 29 in isolation:

- the cron entry arrives on crontab's STDIN, not in argv, so asserting
  on the call log could never have passed for the right reason. The
  stub now records stdin.
- configure_mariadb's stdout is eaten by `db_password=$(...)`, so the
  phase-order marker now goes to stderr and the capture reads both.

Suites now: 28 + 30 + 29 = 87 assertions, 0 failures.

KNOWN AND UNEXPLAINED: kcov mis-measures rpi_nc_install.sh at 10/88 =
11.36%, recording lines 13-54 and nothing after -- yet the code past
line 54 provably runs, since /root/.nextcloud_db_password and
/etc/apache2/sites-available/nextcloud.conf both exist afterwards. The
three obvious culprits were each tested against a minimal reproduction
and DISPROVEN: kcov traces fine past a heredoc, into a $( ) command
substitution, and past a heredoc-fed stub reading stdin via $(cat).
The file stays on the allowlist and the suite is kept for its
assertions, not its percentage. Do not 'fix' the number by weakening a
test.

dot_resolver_install.sh 39/39 = 100.00%; nc_php.sh 84/85 = 98.82%.

61ff5eacac Cover nc_php.sh (98.82%) and teach the jail to measure foreign platforms
nc_php.sh was the next-hardest library on the allowlist. It targets a
Debian Raspberry Pi -- it edits /etc/php/<ver>/apache2/php.ini, drives
occ as www-data and installs a crontab -- so none of its write targets
exist on this Arch host and the jail had nothing to mirror.

- --seed-dir / --seed-file create the paths a foreign-platform subject
  expects. Verified with a probe: /etc/php/8.2/apache2 exists inside
  the jail while /etc/php does not exist outside it.
- A failed bind is now FATAL, and missing mountpoints are created
  first. A bind that fails silently is indistinguishable from
  unreachable code in the report, which is the misdiagnosis this
  runner exists to prevent.
- Mirroring skips unreadable targets (/root as a normal user) rather
  than aborting under set -e.

nc_php.sh: 84/85 = 98.82%, 24 assertions. It STAYS on the allowlist,
because 98.82% is below the bar. Line 111 -- the crontab first-run
fallback -- hung the suite on both attempts to cover it, so it is left
uncovered and documented rather than tried a third time.

Two harness hazards found the hard way and written down: a top-level
stub function shadows the subject's own function for every later
assertion (this silently dropped coverage 83.53% -> 57.65% while the
tests still passed), and a stub for a piped-into command must drain
stdin or the writer takes SIGPIPE.

dot_resolver_install.sh still measures 39/39 = 100.00%.

bca70b67b5 Shell coverage: convert the ratchet to a measured 100% bar
The gate was a presence check -- 'a run_all.sh exists beside this lib' --
which an empty suite that asserts nothing satisfies. It now measures.

100% is reachable with no suppressions and no production source changes:
run the suite inside a user+mount namespace and the sudo-writes, systemd
units and nftables rules execute for real against a throwaway /etc.

- meta/scripts/shell_coverage_jail.sh: the runner, promoted out of a
  session scratchpad. Two fixes it needed on the way: bind targets mirror
  the real directory tree (an empty bind makes writes fail with ENOENT,
  which reads as unreachable code), and sudo gets a pass-through stub
  because real sudo cannot setresuid inside a userns.
- It fingerprints git status before and after and fails the run if a
  write escapes the jail. Verified with a deliberate escapee.
- dot_resolver_install.sh: 39/39 = 100.00%, 28 assertions. Picked by
  scoring every allowlisted lib on root ops, system writes and
  destructive calls -- it scored highest in the repo. Allowlist 106 -> 105.
- jscpd was already over its own threshold at 2.45% and would have
  rejected every commit staging a .sh file. Excluding vendored .venv/
  shell alone gives 1.67%; also excluding lib/tests/ gives 1.47%.

The gate is deliberately NOT wired into the hook chain yet.

d42d8ff20d Shrink the shell-coverage allowlist 115 -> 106: cover scripts/lib
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Gives linux_configuration/scripts/lib a real test suite, which takes all
nine of its libraries off meta/shell-coverage-allowlist.txt at once —
coverage is per-directory, so this is the highest-ratio first batch.

139 assertions across four suites, all offline: the mtk toolkit is driven
through its existing MTK_ROOT_FIXTURE seam, and adb is shimmed onto a
narrowed PATH. Nothing reads the wall clock, this host's udev rules, or a
real device, because the suite runs in shell-tests.yml and again on every
pre-push via ci-mirror — a host-dependent assertion would be a flake that
blocks unrelated pushes.

The gate only checks that tests/run_all.sh EXISTS, so an empty one would
mark all nine libraries covered while testing nothing. Each of the four
load-bearing rules was therefore mutation-tested and the suite required to
go red: classify_device's && -> ||, discover_partitions' init_boot/boot
ordering, mtk_select_device's refusal to guess between two phones, and
is_hour_in_range's 10#$ octal guard.

That last one initially SURVIVED. Dropping 10#$ makes bash abort with
"value too great for base", a non-zero exit indistinguishable from an
honest out-of-range result, so the status-only assertion passed either
way. It now asserts stderr is empty.

d72f03ea93 setup_midnight_shutdown: split into lib/ — the cap is now zero
1734 -> 109 lines across eight libs plus one payload file. This was the last
file over the 250-line cap; check_file_length.sh --all now reports "all
checked files are within 250 lines".

This file needed a different proof from the others. Its product is scripts
generated into /usr/local/bin via heredocs, so "did the functions move
verbatim" is not the question that matters — "does it still emit the same
bytes" is. Every heredoc body was hashed before the split: 11 of 12 are
byte-identical afterwards, and the twelfth (the 224-line config-unlock body)
now lives in lib/payloads/shutdown-config-unlock.sh.in at hash
1a5c67cfd0244101, exactly matching what it replaced. No new bodies appeared.

The "~39 top-level functions" this file is documented as having are not real.
log(), now_epoch(), cmd_add() and friends sit at column 0 because they are
inside the generated scripts. The brace-matching extractor keeps each heredoc
with its owning generator, so they moved as part of it. That is also why
verify_shell_split.sh reports a bare "-log": it cannot tell a heredoc-internal
definition from a top-level one. log() is not lost — it is line 17 of the
payload, which is where it always ran from.

$_MS_PAYLOAD_DIR is defined in the same file as its use, directly above it,
following the _NL_PAYLOAD_DIR lesson from earlier in this campaign.

--help is byte-identical, shellcheck is clean with no suppression added.
`setup` itself is not executed — it installs systemd units, makes the config
immutable and arms a shutdown timer.

fbe9134c22 pacman_wrapper: split into flat libs under the 250-line cap
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
929 -> 217 lines across five pw_*.sh libraries. This file IS /usr/bin/pacman
here (the symlink points at the deployed copy), so the design constraint was
not readability but that no failure mode may leave the machine unable to
install packages.

Fail OPEN, unlike the other splits in this campaign. A missing lib warns on
stderr and execs real pacman unwrapped. Failing closed would mean a missing
lib leaves no way to install anything, including the missing lib. This is the
same choice the existing pacman_lock_lib.sh block already makes, and it is
verified rather than asserted: with pw_guard.sh removed from a scratch-dir
copy, the wrapper warns, execs, and returns real `-Qi bash` output at rc=0.

The libs load at the very top, before the fast path, because the fast path
calls needs_unlock() to decide whether to exec straight through, and that
function now lives in pw_guard.sh.

They are deployed flat beside the wrapper — the shape pacman_lock_lib.sh and
heavy_job_lock.sh already use in /usr/local/bin — as required copies, and are
added to the integrity manifest. Tamper detection was round-tripped in a fake
root: 8 manifest entries verify clean, and appending one line to
pw_challenge.sh is detected and the transaction denied.

Verified by execution, not just textually: real `-Qi bash` and `-Q` through
the split wrapper are byte-identical to the pre-split baseline, same 2824
packages. verify_shell_split.sh reports all 14 top-level functions moved
verbatim.

The deployed copy is deliberately NOT updated by this commit and still hashes
548fc2b5... exactly as before the work started; live pacman is unaffected.
A live `pacman -S` remains unverified — the Bash tool deadlocks on db.lck and
a failed experiment costs the package manager.

Cap is now down to one file.

79a49846b9 setup_night_lockdown: define _NL_PAYLOAD_DIR where it is used
The split referenced $_NL_PAYLOAD_DIR from both install functions but
defined it nowhere, so `setup_night_lockdown.sh setup` would have died
with an unbound variable partway through installing the lockdown. My
earlier scratch verification set the variable by hand, which is exactly
what hid the bug: the emitted artifacts hashed correctly while the real
entry path could not have reached them.

It is now defined in each lib that uses it, eight lines above the use,
via `: "${_NL_PAYLOAD_DIR:=...}"` so an explicit override still wins. A
definition placed in the entry script was silently stripped by an
autoformat pass three times during this work, and a half-run lockdown
installer is not an acceptable failure mode.

Also drops two zero-byte payload files left behind by the .sh -> .sh.in
rename.

Re-verified without presetting anything: install_enter_script and
install_unlock_script emit mode-0755 files hashing 4baaf405... and
eafce28d..., byte-identical to the live /usr/local/bin copies. help and

f6bfdff76a setup_night_lockdown: split into lib/ under the 250-line cap
918 -> 138 lines, across five libs plus two data-file payloads.

The two generated scripts became data files rather than heredocs.
ENTER_EOF alone was 279 lines, so any lib containing it would have been
over the cap however the rest was arranged. Both heredocs were quoted,
so their bodies were already literal text with no build-time
interpolation, and copying them verbatim is exactly equivalent.

The payloads are named *.sh.in on purpose. The pre-commit hook globs
staged files by '\.(sh|bash|zsh)$', runs shfmt -w on them and re-stages
the result -- and shfmt does reformat these bodies. That would have
changed their bytes and destroyed the property this split is verified
by. The .in extension keeps them out of every .sh-globbing hook without
a suppression or an exclude regex.

cat + chmod 0755 became a single `install -m 0755`, closing the window
the original left between creating the file and making it executable.

The load-bearing check: running install_enter_script and
install_unlock_script against a scratch directory produces mode-0755
files whose sha256 sums are identical to the copies already deployed in
/usr/local/bin on this machine. The split provably emits the exact bytes
that are running today, and it touched no system file -- sha256sum -c on
both deployed artifacts passes unchanged.

help, status and an unknown command are byte-identical to their
pre-split baselines. A line-multiset check leaves exactly six lines
unaccounted for: the two cat/heredoc openers, the two terminators and
the two chmod calls that install -m now performs.

72e1b6a8b1 block_compulsive_opening: test the allow/block decision
21 assertions for cco_state.sh, the lib that decides whether a launch is
permitted. Coverage measured: 62/66 lines = 93.94%. The only uncovered lines
are kill_app's pkill/pkill -9 pair, which must never run in a test on a
machine whose apps are live. cco_wrapper/cco_install/cco_report stay at 0%:
every function in them moves system binaries, writes /etc/pacman.d/hooks or
kills processes.

The assertion that matters most is the one in the negative direction: a
PREVIOUS hour's stamp must NOT keep blocking. If that decision inverted, a
legitimately-closed app could never be reopened, and the failure would look
like the tool working. Both directions are pinned, plus the empty-stamp case
and stale suspend-marker cleanup.

Also generalises run_all.sh from test_leechblock_*.sh to test_*.sh. This
directory now holds suites for more than one entry script, and a prefix glob
silently skips every suite added after it — including inside the CI discovery
step added in fbec4656, which runs this file.

The harness asserts its own fixture is complete rather than letting a typo in
a global surface as a confusing unbound-variable from inside the code under
test. That check is also what makes the fixture's globals legible to
shellcheck, which cannot see them being read across the source boundary — a
real check that happens to remove SC2034, not a suppression.

f5edebae4a block_compulsive_opening: split into lib/ under the 250-line cap
705 -> 182 lines, with state, the launch gate, install/uninstall and
reporting moved into cco_state.sh, cco_wrapper.sh, cco_install.sh and
cco_report.sh.

The entry script keeps its exact deployed path and stays a real file
there, not a symlink: the app wrappers already installed on disk
hard-code /usr/local/bin/block-compulsive-opening.sh, and the pacman
hook invokes it. _CCO_LIB_DIR probes for lib/ beside the script and
falls back to the script's own directory, so the repo tree and the flat
/usr/local/bin deploy layout both work; both branches were exercised.

install_all deploys the libs and uninstall_all removes them in this same
commit, so there is never a deployed copy that is split but missing its
libs -- the failure that had to be repaired for install_leechblock.

The libs deploy flat into /usr/local/bin rather than into
/usr/local/share/digital_wellbeing/lib, because install_leechblock_payload
does an rm -rf mirror of that directory and would delete them.

Verified beyond the usual gates: a line-multiset check reports zero
missing functional lines, and all three heredoc bodies -- the generated
app wrapper, the generated pacman hook and the help text -- are
byte-identical, which verify_shell_split.sh cannot check. status output
matches the still-monolithic deployed copy byte for byte.

baeb1119d0 install_leechblock: deploy lib/ alongside the entry script
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
The pacman-wrapper installer copied install_leechblock.sh to
/usr/local/share/digital_wellbeing/ along with three data files, but no
lib/. After the split in 1dceca66 the deployed entry script sources
every install phase from lib/ beside itself, so deploying it without
that directory leaves a copy that dies on its first `source`.

This is not hypothetical: the live deployed copy was found in exactly
that state at the start of this work -- the previous session's split
entry script, deployed and then left behind when the repo was reverted.
It failed on every invocation. It has been repaired and now carries the
libs.

The glob is leechblock_*.sh rather than *.sh because lib/ is shared with
unrelated music_* helpers that have no business in /usr/local. The copy
mirrors rather than merges, so a lib deleted upstream does not linger.

Verified against a fake root and then for real: the deployed copy runs,
its sha256 matches the repo, and inject_default_config resolves the
defaults JSON and the seeder from the deploy root rather than from lib/.

63454fa544 install_leechblock: first test suite for the split libs
29 assertions across two files, run via lib/tests/run_all.sh.

Coverage measured, not waived: leechblock_fetch.sh 38.57% (27/70),
leechblock_browsers.sh 36.47% (31/85), config and firefox 0%. The uncovered
lines are exactly the bodies that must never run under test — curl/tar/unzip
downloads, pkill + sudo binary patching, npm install, and writes to
/etc/*/policies.json. Closing the gap needs those externals shimmed.

What the tests actually pin down:
- all three get_latest_tag fallbacks (releases API, tags API, Location
  header), plus JSON-null-is-not-a-tag and the all-sources-exhausted
  non-zero return. A silent failure there installs the wrong version.
- the 8+3 browser tables including every hyphenated key, and the
  command -v gating that decides whether a binary is patched at all.

Also fixes a latent set -u abort: wire_up_browsers interpolates VERSION_DIR,
VERSION and TAG, which only resolve_version sets. Calling it on its own
aborted on an unbound VERSION_DIR; they are now read through locals with
defaults, leaving production output unchanged.

Harness note: PATH must be narrowed to the shim dir for "no browser
installed" to be testable on a machine that has five, but every external the
code under test calls has to be seeded there too — a missing mkdir aborted
the suite under set -e with no stderr, which under kcov looked like a
coverage-tool bug rather than a PATH bug.

The hyphenated array subscripts in the test are quoted for the same reason
they are in the lib: shfmt -w rewrites an unquoted [google-chrome-stable]
into a subtraction expression. Reproduced live in this file during the work.

1dceca6600 install_leechblock: split into lib/ under the 250-line cap
485 -> 114 lines, with the six install phases moved into four sourced
libs: leechblock_fetch.sh, leechblock_config.sh, leechblock_browsers.sh
and leechblock_firefox.sh.

detect_browsers, replace_browser_in_place and wire_up_browsers stay in
one lib on purpose: detect_browsers writes the BROWSERS/FIREFOXES arrays
that wire_up_browsers reads, and splitting them would create a
write-only cross-file global.

Four justified body changes, all recorded in the evidence:

- Quoted the six hyphenated associative-array keys. shfmt 3.13.1 parses
  an unquoted [google-chrome-stable] as arithmetic and rewrites it to
  [google - chrome - stable], which would break browser detection
  entirely. The pre-commit hook runs shfmt -w on staged files and
  re-stages them, so this corruption would have landed in the commit
  unseen -- this is what caused the previous attempt at this split to be
  reverted. Behaviour-preserving: quoted and unquoted are the same key.

- SCRIPT_DIR is assigned in the entry script rather than inside
  inject_default_config. Left in the lib, ${BASH_SOURCE[0]} resolves to
  lib/, so the defaults JSON lookup would miss and default blocking
  rules would silently never be seeded.

- install_firefox_policy takes ff_found as a parameter instead of
  reading it as a cross-file global, fixing a genuine SC2154 without a
  suppression.

- Added require_cmd unzip. It was used bare under set -Eeuo pipefail, so
  a missing unzip would abort after the version dir was populated but
  before the 'current' symlink was made, leaving a half-installed tree.

verify_shell_split.sh reports additions only -- no -/+ pair -- so
get_latest_tag and replace_browser_in_place moved byte-identically.
--help and unrecognized-flag output are byte-identical to the baseline.

47478791d8 hosts/install: split into lib/ under the 250-line cap
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
913 lines down to 150. The ten functions were only 202 lines; the other 712
were a single top-level block, now eight phase functions across six libs. As
in the previous split the bodies were wrapped WITHOUT re-indenting, because
five heredocs use quoted terminators that must stay at column 0 (shfmt
indented them afterwards, which is safe).

The ~320-line custom-blocklist heredoc became custom_entries.hosts. It was
321 of the 370 lines of hosts_write.sh and cannot be split, so that lib could
not otherwise fit the cap; a hosts-format data file is also far easier to
audit and diff than a quoted heredoc.

That move broke a guard, which is the important part of this commit:

  extract_custom_entries_from_script sliced the blocklist out of the script
  between "# Custom blocking entries" and the heredoc terminator. With the
  entries in a data file there is no terminator, so it would have extracted
  NOTHING -- and check_custom_entries_protection, the guard whose entire job
  is refusing to drop blocked domains, would have compared against an empty
  list and passed everything. It now reads the data file, and the extracted
  set is identical: 254 domains, diffed.

A second, pre-existing bug surfaced while testing:

  extract_unblock_entries_from_script matched its OWN marker lines.
  PROTECTED_UNBLOCK_LIST_START and _END are word characters, so the
  '^# [a-zA-Z0-9._-]+$' pattern pulled both into the whitelist as if they
  were domains. Both are in this machine's live state file right now.
  Renaming either marker would have read as the whitelist growing and blocked
  the install outright.

There is no dry-run or status mode, so this file cannot be proven by running
it: an aborted run leaves /etc/hosts mutable with the guard's bind mount down.
The proof is textual instead. Every one of the 8 wrapped phase bodies is
byte-identical to its original line range; a line-multiset check found 0 lines
lost; and an indentation-insensitive comparison against the pre-split file
leaves exactly 8 absent lines, each an intentional edit (the rewritten
extractor, three `readlink -f "$0"` made overridable, the /etc/hosts fallback
made overridable, and the heredoc markers). /etc/hosts is byte-unchanged
across the whole session, and `--help` output is identical.

36 assertions. Both anti-tamper guards at 100% line coverage (75/75 and
49/49), covering both directions of each: removing a blocked domain is
refused and adding one allowed; growing the whitelist is refused and shrinking
it allowed. A same-count swap is refused too, which a count-only check would
have let through.

The install phases themselves are deliberately untested -- running them would
take down the protection they install. That is weaker evidence than the two
previous splits had, and it is inherent to this file rather than a gap.

241652cade generate_study_materials: split into lib/ under the 250-line cap
1017 lines down to 148. Six libs: the per-language doc-URL builders (split in
two only for the cap), the lookup/dispatch layer, and one per generation phase.

The hard part was not the ten functions but the 335-line top-level block,
which extract_shell_functions.py cannot move because it only relocates
functions. It is now generate_doc_links / generate_anki_cards /
generate_llm_prompt, wrapped WITHOUT re-indenting the bodies: five heredocs
use quoted terminators, which must stay at column 0.

Proof the split is behaviour-preserving: a golden fixture captured before any
edit, re-checked after every step. All three outputs -- anki_cards.txt,
documentation_links.md, llm_anki_prompt.md -- stay byte-identical by sha256sum,
and stdout matches too.

Four latent defects surfaced while writing the tests, all fixed:

  python_doc_url required a $2 it never reads, and get_doc_url has always
  called it with one argument. That only worked because the entry script runs
  `set -e` without `-u`, so "$2" silently expanded to empty; any caller with
  `set -u` aborted. Defaulted, along with three more positionals documented as
  optional but declared required.

  The two imports loops hardcoded `head -20` while the other seven honoured
  TOP_N, so --top was silently ignored for imports.

  Only one of nine term loops skipped comment lines, so a '#' line in an
  analysis file became a flashcard whose front was a comment.

  Introduced and fixed within this change: the comment filter has to run
  BEFORE `head -n` or comment lines count against the limit, and it needs
  `|| true`, since grep exits 1 when it filters every line and the callers run
  under `set -e`.

The golden fixture cannot show the last three, because it has no comments and
fewer than 20 imports -- which is exactly why they survived. A second fixture
with 25 imports and comment lines, at --top 3, emitted 20 imports and two
comment cards before, and 3 imports with zero leakage after.

166 assertions across 4 test files. 100% line coverage on study_doc_urls.sh
(38/38), study_doc_urls_more.sh (30/30), study_doc_lookup.sh (49/49) and
study_gen_llm.sh (54/54). study_gen_docs.sh 93.10% and study_gen_anki.sh
96.15%, where every remaining line is a `} >>"$FILE"` closing a brace group
whose output a passing test asserts -- the same kcov attribution artifact
recorded for services_hosts.sh.

08f3c764b2 check_and_enable_services: a warning must never mask an error
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Eight checks assigned status="warning" unconditionally, so a check running
later in the same function overwrote the status="error" an earlier one had
set. The five other sites in this family already guard the assignment with
`if [[ $status != "error" ]]`, so this was an inconsistency, not a design.

Only half of it was load-bearing, and the two halves fail differently:

  services_units.sh (4 sites) reports through report_and_fix, which repairs
  ONLY on "error". A downgrade there meant no repair ran at all. The is-active
  check is the LAST status assignment in each of the three functions, so it
  could mask any error above it -- in check_periodic_systems, three separate
  is-enabled checks. A timer that was both disabled and inactive, which is the
  ordinary shape of a broken timer, was reported and then left broken.

  services_hosts.sh (4 sites) gates its own repair on `status != "ok"`, so the
  repair still ran. There the bug printed a real error as a yellow [!] warning
  and understated the summary row.

Demonstrated rather than argued, against a simulated broken machine (timer
disabled AND inactive, unit files present):

  without the guards:  status=warning, repair ran 0 times
  with the guards:     status=error,   repair ran 1 time

The seven assertions that previously pinned the broken behaviour now assert
the correct behaviour; they were rewritten first and failed, then the guards
made them pass. Two further cases cover the masking shape directly: a broken
guard-lib instance must still be repaired when a later check warns.

`--status --dry-run` output is still byte-identical to rev 6691cb26, because
this machine has no disabled timer and no missing pacman hook -- the buggy
path is never taken here, which is precisely why it went unnoticed. The A/B
above is the evidence the live diff cannot provide.

222 assertions across 10 files. services_units.sh holds 100% coverage;
services_hosts.sh rises from 86.05% to 93.02%. test_services_hosts.sh needed
splitting twice to stay under the 250-line cap (hosts_fix, resolved), and
stage_hosts_ok moved into the harness so both new files can use it.

0a69d18390 check_and_enable_services: 100% coverage via a redirectable path prefix
Follow-up to 9085a4e5, which recorded services_units.sh at 84.51% because
its remaining branches sit behind [[ -f /etc/systemd/system/*.service ]] --
absolute root-owned paths that exist on this machine, so the else-branch
never runs and no PATH shim can redirect it.

All 87 such paths across the seven check libs now go through $SYSROOT, read
from SERVICES_ROOT. The prefix is deliberately NOT defaulted. Three commands
in hosts_fix_resolved run outside `run` and so are not stopped by --dry-run
(chattr -i on resolved.conf.d, find -delete over its *.conf, and an append to
resolved.conf); with an empty default, a test that forgot to set SERVICES_ROOT
would really delete this machine's resolved.conf drop-ins. Unset is therefore
a hard error and only an explicitly empty value means the real filesystem.

The harness now owns PATH outright: $FAKE_BIN for shims and staged fake apps,
$REAL_BIN for a curated set of symlinks to genuine coreutils. The machine's
/usr/bin is deliberately absent -- a really-installed discord and chromium
otherwise make the "no target apps present" branches untestable, which is
exactly what happened until these tests caught it.

Coverage, measured against run_all.sh because two test files jointly cover
services_common.sh after the 250-cap split: common 55/55, report 27/27,
units 72/72 (was 84.51%), wrappers 100/100, apps 66/66, browser 79/79 --
seven libs at 100%. services_hosts.sh reads 86.05% and services_hosts_fix.sh
97.30%, and those 14 lines are a kcov attribution artifact rather than a gap.
Falsified rather than assumed: the suite prints "51 passed, 0 failed" when run
under kcov, so no group is skipped, and every supposedly-uncovered line is an
issues+=("...") whose string can only reach stdout through the print loop
below it -- with a passing assertion matching that exact string.

Two falsification checks, both re-run after the rewrite: `--status --dry-run`
as root stays byte-identical to rev 6691cb26 modulo the Date: line, and the
sha256sums of /etc/hosts, /etc/nsswitch.conf and /etc/systemd/resolved.conf
plus the contents of resolved.conf.d are unchanged across a full suite run.
The second one is what makes a missed prefix site detectable instead of a
matter of inspection: the repair paths really do write.

220 assertions across 8 test files. Also fixes a bug in the harness's own
lsattr shim, where printf with a leading-dash format string parsed the dashes
as options and silently produced nothing.

9085a4e508 check_and_enable_services: split into lib/ under the 250-line cap
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
1225 lines down to 202, with the 21 functions moved into eight sourced
libraries grouped by subject. The entry script now holds only the
configuration, the argument parsing and the order the checks run in.

check_hosts was the one function that could not move verbatim: at 260 lines
it would have stayed over the cap on its own, so its repair half is now
hosts_fix_nsswitch / hosts_fix_resolved / hosts_repair_all in
services_hosts_fix.sh. Repair order is preserved (resolver config, then the
hosts file, then the guard-lib migration), and hosts_repair_all returns
non-zero under --dry-run so a dry run can no longer promote a status to "ok"
on the strength of repairs that never happened.

SERVICE_STATUS was a write-only global across five libs, which is a real
SC2034 rather than noise: the pre-commit hook runs shellcheck with no -x and
genuinely cannot see the one reader. It now goes through set_service_status /
get_service_status, which also rejects a duplicate write — each check owns
exactly one summary row, so a second write means two checks are fighting over
it. No suppression was added anywhere.

Proof the behaviour is unchanged: `--status --dry-run` run as root against
this machine is byte-identical to the same command from a worktree at the
pre-split revision, modulo the Date: line. verify_shell_split.sh reports
check_hosts as the single expected difference; the other 20 functions hash
identically. 72 assertions across three test files pass, with 100% line
coverage on services_common.sh (54/54) and services_report.sh (27/27).

services_units.sh measures 84.51% (60/71). The 11 uncovered lines are the
else-branches of [[ -f /etc/systemd/system/*.service ]] and
[[ -f /usr/local/bin/*.sh ]] probes — absolute root-owned paths that exist on
this machine and that no PATH shim can redirect. Reaching them needs a
root-prefix rewrite of live enforcement logic, which is not a line-count fix
and would forfeit the verbatim-move proof for everything else.

Found while testing, deliberately NOT fixed here: in all three unit checks
the is-active branch assigns status="warning" unconditionally, overwriting
the status="error" the is-enabled branch set just above it. A timer that is
both disabled and inactive therefore never gets repaired, because
report_and_fix only repairs on "error". It is identical in the pre-split
file, so this split neither caused nor hides it. The tests pin the current
behaviour and name it; fixing it changes enforcement and earns its own commit.

once the directory was surveyed. Full history preserved via git filter-repo,
live at github.com/kuhyx/testsAndMisc-archive/tree/main/linux_configuration/scripts/periodic_background/hosts/guard.
plugins/{nsswitch,resolved}-plugin.sh stay - they're guard-lib's live
plugins, referenced by absolute path from /etc/guard-lib/targets/*.conf.

check_and_enable_services.sh's check_hosts() rewritten to check guard-lib
state (guardctl file-guard status) instead of the retired units/scripts it
used to check and self-repair - verified live, now reports the hosts

015eb48714 diagnose_pacman_hook_stall.sh: split 493 -> 249 + 6 libs, 100% coverage
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Confirmed live (not dead code) via the dead-code check-in before any code
was touched -- the last two candidates this pattern was tried on were both
archived instead. Kept run_one/cleanup/log_size/main together in the entry
script: a prior session (2527fb3) already proved splitting run_one out
produces a real SC2153/SC2034 pair since PACMAN_PID/LAST_ELAPSED cross the
EXIT trap, not a suppressible false positive.

Fixed a real bug found while writing tests: print_summary's inline awk had
a dead `NR == 0` guard (printf on an empty array still emits one blank
line), reachable via `-n 0`. Refactored mem_available_mb, descendant_pids/
kill_tree, capture_stall's two output blocks, and print_summary's median
calc after confirming empirically (bash -x tracing) that kcov's
xtrace-based coverage can never see a `done <redirect>`, `} >redirect`, or
inline-awk line -- user chose to fix the code over the coverage tool.
descendant_pids specifically needed an explicit-fd process substitution
(not a pipe) to keep its array mutation in the current shell.

Made PACMAN_BIN/PACMAN_LOG/CACHE_DIR/PACMAN_LOCK/LOAD_FLOOR_MB/
LOAD_MIN_FREE_MB env-overridable for testing. Caught and fixed, before it
ran unbounded, a --with-load test that would have dd'd 13-20+ GB into
/dev/shm using this box's real available memory.

56 lib-level + 13 entry-level PATH-shim/subprocess assertions, 0 failed.
The entry test itself grew past 250 lines while adding coverage and had to

2a7b9d90ac install_plagiarism_tools.sh: split 534 -> 94 + 3 libs, with a real test harness
Wraps the four install stages into named functions, one per lib/plagiarism_*.sh
sibling (matching install_exercism.sh's convention), and extracts the two
embedded Python heredocs into real, lint-clean check_plagiarism.py/sherlock.py
files -- check_plagiarism.py needed a second split into plagiarism_similarity.py
to also clear the 250-line cap. Every function reaches 100% shell coverage via
a PATH-shim test harness (fake python3/pip/git/java/wine); the two Python CLIs
were separately verified against a real venv with actual nltk/scikit-learn.

2c95425a60 steam_compatibility: split 663 -> 140 + 199 + 156 + 124 + 103
Grouped by the state each function touches rather than by size:

  steam_requirements.sh  199  requirement parsing, scoring, and the hardware
                              detection that feeds it
  steam_report.sh        156  the run loop and the cache it reads
  steam_api.sh           124  library discovery, Steam and ProtonDB calls
  steam_credentials.sh   103  credentials, usage text, presentation helpers

The grouping was forced by the SC2034 writer/reader rule, not chosen. Two
arrangements were discarded: detect_system alone in a lib writes the three
SYSTEM_* globals without reading them, and load_cache_map alone writes
CACHE_MAP without reading it. Both were fixed by putting the writer next to
its reader - detect_system beside score_game, load_cache_map beside main.

Verified: all 33 functions verbatim; every lib passes shellcheck standalone
with no suppression; and the script actually runs - `--help` prints the usage
block and exits 0, which is what proves the four source lines resolve and
main still dispatches.

Over-cap files 26 -> 25.

76e73830f6 shell: split clean_audio, enforce_vbox_hosts and migrate_hosts_guard
clean_audio.sh          419 -> 230 + 204
  enforce_vbox_hosts.sh   443 -> 220 + 236
  migrate_hosts_guard.sh  444 -> 167 + 162 + 141

migrate_hosts_guard needed two libraries: with all ten work functions moved
the single lib was 295 lines, so migrate and rollback were separated.

The extractor's brace matcher required index > start and so silently skipped
one-line `warn() { ...; }` definitions. Fixed, and regression-checked against
the committed fresh-install/main.sh split byte-for-byte.

The harness earned its keep on a fourth file: adding `export` to libre_translate
to satisfy SC2034 changed two function bodies, and verify_shell_split.sh caught
what lint had accepted. Those exports were reverted, and libre_translate.sh is
parked - what remains after its clean seams both assigns and reads the same
globals, so getting it under the cap needs parse_args restructured rather than
relocated, which is a refactor rather than a verbatim move.

That cost is now written down: a lib must contain the readers of every global
it assigns. The precedent at install_pacman_wrapper.sh:29 is about
definitions-only libs, not about assignments as such, and the pre-commit hook
runs shellcheck with no -x, so a source= directive will not make it follow the
link. This is the shell analogue of the monkeypatch-target trap.

Verified: all 8, 13 and 19 functions verbatim; all four libraries source with
no side effects; shellcheck passes standalone on every file with no
suppression; bash -n passes on all seven. None of the three was executed -
they drive ffmpeg over real media, mutate VirtualBox guest disks, and rewrite
systemd units.

Over-cap files 29 -> 26.

efd7f022fd fixes/utils: split nvidia_troubleshoot 336 -> 169+181, passwordless 374 -> 195+193
Two single-use scripts with no deployed copy, so the entry+lib shape is
safe. Each keeps the ordering, the safety checks and the user-facing output;
the configuration writers move to a library beside it.

Both scripts write `set -e # Exit on any error`, so extract_shell_functions.py
now matches the directive rather than the whole line. Regression-checked by
re-deriving the committed fresh-install/main.sh split byte-for-byte.

Verified: all 6 and all 9 top-level functions verbatim via the shfmt
harness; both libraries source with no side effects and define every
function moved into them; bash -n passes on all four.

Neither script was run. nvidia_troubleshoot.sh writes /etc/X11 config and
installs pyroveil; setup_passwordless_system.sh writes sudoers and lightdm
autologin, which is what this machine's login depends on.

Over-cap files 31 -> 29.

9b30329ca3 fresh-install: split main.sh 308 -> 200 + 121
The five package-installation functions move to lib/packages.sh; main.sh
keeps the top-level flow and sources the library after `set -e`.

The first attempt sliced by line range and was thrown away. This file
interleaves top-level commands - sudo -v, git config, the cp of
makepkg.conf and pacman.conf - between its function definitions, so a range
slice swept them into the library, where they would have run at source time
and in the wrong order. Sourcing that version blocked on a sudo password
prompt, which is how it was caught. The rebuild extracts function blocks by
brace counting and leaves every other line exactly where it was.

Verified with the new shfmt harness (all 5 functions verbatim), by a
structural comparison of the top-level flow showing exactly one line added
and none missing, and by sourcing the library to confirm it defines all five
functions with no side effects. The script itself was NOT run: it does
`sudo pacman -Sy`, overwrites /etc/makepkg.conf and /etc/pacman.conf, and
installs AUR packages.

Over-cap files 32 -> 31.

dbf2f29b00 _transcribe_diarize: split 356 -> 164 + 143 + 105
The last Python file over the cap:

  _transcribe_media.py    143  _try_import, both duration probes,
                               get_media_duration, ffmpeg transcode, cleanup
  _transcribe_cluster.py  105  _resample_linear, _kmeans_cosine and its
                               iteration loop
  _transcribe_diarize.py  164  the pipeline: audio loading, the classifier,
                               embedding extraction, diarize_segments

The graph is a tree: _transcribe_media imports nothing local, _cluster takes
only _try_import from it, _diarize imports from both. All 13 top-level
definitions verified AST-identical to HEAD, and an AST scan confirms the
three module constants travelled to the modules that use them.

transcribe_fw.py now imports get_media_duration from _transcribe_media
rather than through _transcribe_diarize. Ruff removed that re-export as
unused and broke the import; running the program is what caught it, and
naming the owning module is the correct fix under the no-barrels rule.

Verified: transcribe_fw.py /nonexistent.wav still exits 2 and --help exits
0; 63 tests pass at 100% line and branch on all three modules; 338 pass in
the directory. Over-cap files 33 -> 32, and no Python file is over the cap
any more - the remaining 32 are 29 shell, 2 kotlin, 1 dart.

Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
_transcribe_progress.py   91  _run_progress_loop, _format_progress_line,
                                and the two constants only they use
  transcribe_fw.py         236  argument parsing, model loading, diarized
                                output writing, main

All 8 top-level definitions verified AST-identical to HEAD, and an AST scan
confirms neither module references a name it does not bind - which is what
caught that the two progress constants and the hhmmss import had to travel
with the loop. transcribe_fw.py no longer imports time.

The progress tests now patch _transcribe_progress, including its sys.stderr
and time references, since that is where the loop resolves them.
_resolve_device_and_compute stayed behind, so its test still points at
transcribe_fw.

Verified: --help prints the full usage and a missing input returns exit 2,
the code transcribe.sh branches on; 32 tests pass at 100% line and branch on
both modules; 275 pass in the directory. Over-cap files 34 -> 33.

bda24b6305 transcribe_helpers: split 289 -> 177 + 142
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Split along the natural seam now that the file is fully covered:

  _transcribe_probes.py  177  _try_import, the four dependency probes,
                              generate_sine_wav, prepare_model, test_cuda
  transcribe_helpers.py  142  the eight _handle_* functions and main()

All 18 top-level definitions verified AST-identical to HEAD, and an AST
scan confirms neither module references a name it does not bind.

transcribe.sh is untouched - it invokes tools/transcribe_helpers.py by
path, and that path still exists with the same name and executable bit.
The CLI tests' patch targets did not move either, because main() dispatches
to names imported into its own namespace.

Verified by running every subcommand and reading the exit status directly,
since those codes are the contract transcribe.sh branches on:
python-version 0, check-faster-whisper 7, check-ctranslate2 1,
check-diarization 0, deps-installed 0; generate-wav writes the same
96044-byte WAV as before the split. 41 tests pass at 100% line and branch
on both modules; 243 pass in the directory. Over-cap files 35 -> 34.

57b9005a6b usage_report: delete the dead _compute_window shim
Documented as "kept for backwards import compatibility", it had zero
production callers - only its own two tests. Removed the function, those
two tests, and the pathlib.Path import that only its signature used.

_SEC_PER_DAY stays: two live callers remain at _usage_report_run.py:135
and :181, so only the function was dead, not the constant.

Verified: usage_report.py --help exits 0 (the unit tests stub subprocesses,
so only a real run proves the import graph), 202 tests pass, and
_usage_report_run.py holds 100% line+branch coverage after removing both
the code and the tests that covered it.

ff1a1b6a0e usage_report: split usage_report.py 426 -> 101 + 195 + 117 + 68
The entry point now holds only the parser, mode dispatch and main. Three
modules take one concern each: _usage_report_logs (where the logs are,
the state file, per-day segment planning), _usage_report_emit (preflight,
stdout, clipboard), _usage_report_run (the two run paths and the
aggregation they drive).

Verified by the 100%-coverage tests from the previous commit. An AST
comparison of all 22 top-level defs and classes reports 22 identical, 0
mismatches.

All four modules hold 100% line+branch. 204 tests before and after. Both
CLI modes were run against the machine's real logs, which is the check
the unit tests cannot make: they stub the collaborators, so only a real
run proves the new import graph resolves.

Two lessons, recorded because the next target is a 498-line file:

This cut was too big. Two names had to be relocated after their first
placement created an import cycle, and four modules' worth of monkeypatch
targets needed re-pointing. A smaller first slice would have been cheaper.

Patching a moved function must target the module whose namespace resolves
it - the caller's, not the one it was moved to. Getting that wrong on
_run_since made main() call the real function, which read the actual atop
logs and hung the suite rather than failing.

Three import bugs (Path and _fmt_h left under TYPE_CHECKING but used at
runtime, dataclass missing where _Aggregates landed) were caught
immediately by the coverage from the previous commit.

Over-cap 38 -> 37.

Shell tests / arch-tests (push) Waiting to run
Lifts the atop subprocess machinery into _usage_report_atop.py: running
atop, streaming its parseable output, building/caching the atop_agg C
helper, and reading its TSV. What stays is record parsing, epoch windows
and per-day merging.

Verified by the 100%-coverage tests from the previous commit. An AST
comparison of all 16 functions against HEAD reports 16 identical, 0
mismatches.

_usage_report_render.py imported _run from the parsing module; it now
imports from the module that owns it. That is the same re-export barrel
the last split shipped and had to fix in a follow-up - caught in the same
commit this time. usage_report.py needed no edit at all.

Both modules hold 100% line+branch (94/28 and 130/34, 0 missed). 179
tests before and after; the five new test files collect 8+6+4+14+5 = 37,
which is last commit's 36 plus the one re-homed out of
test_usage_report_modes.py, where it referenced a constant that had
moved out from under it.

The two test files added last commit were themselves over cap (373, 272)
so they are split five ways here - the DropZone lesson from earlier
today, where a lint fix silently added an over-cap file.

Ran the program: a real report from today's logs, through the native
atop_agg path, which is precisely the code this commit moved.

Over-cap 39 -> 38.

efb471fc8b usage_report: import _fmt_h from its owner, not through the render module
The previous commit's message claimed "no re-export barrel". That was
wrong: usage_report.py still did

    from _usage_report_render import _fmt_h, _render_report

and after the split _fmt_h lives in _usage_report_format - the render
module only re-imports it for _methodology_section. So the import reached
the owner through an intermediary, which is the exact pattern the brief
says was vetoed last session. Now each name comes from its own module.

Also untracks bucket_catch/packages/frontend/tsconfig.tsbuildinfo and
gitignores *.tsbuildinfo. It is a generated incremental-build cache
tracked in a repo that blocks binaries, and it has been dirty in every
commit this session, forcing pre-commit to stash each time.

143 tests pass; usage_report.py still generates a real report.

Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Python tests / test (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
Verified by the 100%-coverage tests from the previous commit, written
before this seam existed.

_cpu_table/_dedupe_ram/_ram_table/_gpu_table move to
_usage_report_tables.py with the two constants they own. _md_escape and
_fmt_h move to _usage_report_format.py: both the tables module and the
render module need them, so a third module is what avoids a cycle.
Import sites name the owning module; no re-export barrel.

usage_report.py needed no edit - it imports _fmt_h and _render_report
from the render module, and both names still resolve there.

Evidence the move was verbatim: an AST comparison of all 10 functions
against HEAD reports 10 identical, 0 mismatches. That matters because I
retyped rather than cut-and-pasted, and did briefly introduce a literal
× where the original had × - ruff's RUF001 caught it.

Coverage stays 100% line+branch on all three (15/55/54 stmts, 4/10/14
branches, 0 missed). Test count 43 before and after, summed across the
five files it now lives in - the check that matters for a test split,
since a file outside the runner's glob is silently never collected.
Directory total 143 passed, unchanged.

Ran the real program: a full report from today's atop + pmon logs, every
section rendering through the new boundaries including the RAM sibling
dedupe and its (+20 more) truncation.

Over-cap 41 -> 39. No suppressions; a shared test-helper module was tried
and abandoned because name-tests-test would have needed an exclusion.

5dce82f2c7 Remove the dead Thorium/Fitatu autostart instead of splitting it
Some checks are pending
Pre-commit checks / pre-commit (push) Waiting to run
Shell tests / shell-tests (push) Waiting to run
Shell tests / arch-tests (push) Waiting to run
setup_thorium_startup.sh (443 lines) was queued for a split under the 250-line
cap. It turned out the feature it installs has been broken since Thorium was
removed in favour of chromium/librewolf.

/usr/local/bin/thorium-browser is now only a leftover symlink to
browser-preexec-wrapper, which routes by basename to /usr/bin/<name>. With no
/usr/bin/thorium-browser it falls into its testing branch and treats the URL as
the binary, so every boot logged:

  thorium-browser: line 33: /https://www.fitatu.com/app/planner: No such file

while systemd reported status=0/SUCCESS and "Finished". The success status is
why this went unnoticed.

Splitting a 443-line script to keep a dead feature under a line cap is the
wrong work, so it is deleted instead, along with its checker.

Removing check_thorium_startup() from check_and_enable_services.sh is the part
that makes this stick: its report_and_fix RE-RAN the installer whenever the
service was not enabled, so deleting only the deployed units would have let
them come back. Verified afterwards that the hourly maintenance timer runs a
deployed script with no thorium reference, and that nothing on a timer invokes
the checker at all.

Also removed from fresh-install/main.sh so new machines skip it. Units disabled
and all four deployed files removed. The generic browser-candidate lists that
merely mention thorium are left alone.

4eedc17b17 Split install_pacman_wrapper.sh into an entry plus four libs
The 316-line installer was 66 over the 250-line cap. The managed-copy helpers,
the /usr/local/bin install step, the integrity + drift manifest, and the
immutability/LeechBlock/VirtualBox payloads move into a sibling lib/, leaving a
128-line entry.

What stays in the entry is chosen by what the harness can execute, not by
taste. `--bind-abs /usr/bin` removes the directory bwrap needs to exec
anything, so the trace stops at `ln -sf ... /usr/bin/pacman` with exit 1 on
EPERM. That line onwards, plus the `if [ ! -L /usr/bin/pacman ]` backup branch
whose guard is false on this machine, therefore never run under trace — moving
them would have shipped code no diff could check. They stay put.

Everything else is proven: the before/after traces are identical, including all
16 generated-file hashes. pacman_wrapper at 548fc2b53ee4cea6 is the one that
matters most — it is post-`sed -i`, so it catches a reorder of the rewrite
relative to the copy.

The path definitions stay in the entry too, for a linter reason rather than a
runtime one: a definitions-only lib assigns without referencing, which is
SC2034 on 36 variables, and suppressions are not allowed. Libs that only
reference globals are fine. `export` would have silenced it while leaking 40
variables into every child process, which the trace cannot see.

Eight assertions across two test libs grep the installer's source text; five
needed widening to search entry+lib/. TEST 9's `chattr +i` grep caught the move
as a genuine failure first, which is what prompted enumerating the rest. No
assertion was weakened.

26965bad32 Split install_usage_monitoring.sh into an entry plus five libs
The 290-line installer was 40 over the 250-line cap. Its five banner-marked
steps move into a sibling lib/, leaving a 53-line entry that owns log()/die(),
the globals that cross between steps, and the call order.

Proven by execution, not inspection: meta/scripts/trace_shell_split.sh
--prefix was captured at HEAD in place (tracing from a detached worktree
changes REPO_DIR, which is interpolated into a generated file, and fakes a
diff), then re-run after the split. The traces are identical -- same exit
status, same ordered stubbed calls, and all five generated-file hashes
unchanged, including usage-report-catchup.sh at sha=9f4803ab157c5527.

REPO_DIR is computed once in the entry and read as a global rather than
recomputed inside a lib one directory deeper; recomputing it would have
pointed the generated catch-up script at the wrong repo while still exiting 0.

test_usage_monitoring_installer_efficiency.sh greps the installer's source
text for the pmon heredoc, so it follows that heredoc to lib/nvidia_pmon.sh.
Its extraction anchor also had to become whitespace-insensitive: the
pre-commit hook runs `shfmt -w` on staged shell files and rewrites
`cat > "x" << 'SCRIPT'` to `cat >"x" <<'SCRIPT'`, which silently broke
extraction. All five property assertions are unchanged.

4ff7a0bf15 Split mtk_root run_tests.sh: assertions and the dump-test group
421 -> 218 + 157 + 75. The assertion helpers (pass, fail, assert_*,
strip_noncode, run_recon) go to lib/assertions.sh; the six
20-dump-stock.sh tests go to lib/dump_tests.sh. run_tests.sh keeps the
counters, the trap, the eight recon tests and main().

Verified by running the suite, not by inspecting it: 58 passed / 0 failed
before and after, and a diff of the complete 89-line output reports no
differences. The suite is hermetic -- every test drives a fixture via
MTK_ROOT_FIXTURE -- so this is a real execution of 58 assertions rather
than a stubbed trace.

All three files are shfmt-dirty, but run_tests.sh already was at HEAD
(2-space indent against shfmt's tabs) and the libs inherit that style, so
no clean file was made dirty.

1b19808edb Keep this session's splits shfmt-clean
analyze_repo.sh was shfmt-clean at 133fccf and my split made it dirty
(a double blank line). Fixed with shfmt -w, then restored the STEP 1
comment banner shfmt -w also stripped -- all eight banners re-counted.

The three new shell_check libs inherited their parent's 2-space
indentation; as new files they have no prior style to preserve, so they
are now tabs like shfmt wants.

Context for the exit code: 157 of 298 linux_configuration shell files
already fail shfmt at 133fccf. shfmt is not in .pre-commit-config.yaml
and there is no .editorconfig, so run_linters exiting 1 on the full tree
is the repo's standing state, not a regression here. Scoped this commit
to what these splits touched rather than reformatting 157 files.

Also closes the risk left open in a84556a: run_linters now verified
directly over the three new libs -- all six passes PASS, exit 0 -- with
install_linters never invoked, so decision 6 holds. That is the path
.github/workflows/shell-check.yml runs.

936e0ec70d Fix two runtime defects the analyze_repo.sh split introduced
41cc045 passed bash -n, shellcheck, a function-set diff, a line-set diff
and a stubbed source run -- and still shipped a script that aborted after
language detection. Both bugs needed a real execution to see.

1. set -e. The eight `((LANG_FILES[x] > 0)) && HAS_Y=true` lines were
   top-level statements, where a false `&&` merely left $? non-zero. As
   the tail of detect_languages they became its return value, and the
   last one (java, false for most repos) killed the script. Now `|| true`.

2. Self-referencing nameref. `local -n LANG_CODE_FILES="$1"` pointing at
   a global of the same name makes bash 5.3 warn "circular name
   reference" on every access -- into this script's own output. The
   locals are now _code_files.

The rename then hid the array from shellcheck (SC2034), since it was only
named as a bare word. Fixed by passing it through CODE_FILES_MAP so the
reference is real, not by suppressing.

Verified against 133fccf end to end on a fixture repo: same file set,
every text artifact byte-identical, exit 0 both sides, zero warnings.
Only cscope.out.in differs, in binary padding -- same input list, same
90112 bytes.

The lesson for the recipe doc: a stubbed run sources the libs and never
calls them, so it cannot reach a bug in a seam that passes state.
